Weather Summary for Eastern Nebraska and Southwest Iowa
National Weather Service Omaha/Valley NE
317 PM CDT Tue Apr 25 2017
A cold front moved through eastern Nebraska and most of southwest
Iowa Tuesday morning and afternoon, dragging much cooler air in
behind it. A few showers fell behind the front as an upper level
weather system rode over the cooler air, but by mid afternoon, most
of the rain had slipped north of northeast Nebraska. Temperatures at
3 PM ranged from a chilly 40 degrees at Norfolk to a more mild 70 at
Clarinda. North winds averaged 15 to 25 mph through the afternoon.
A low pressure system stretching from eastern Iowa into Oklahoma will
be the focus for showers and thunderstorms overnight tonight. Strong
thunderstorms are expected to develop from eastern Oklahoma through
southeast Kansas and western Missouri. Farther north and northwest,
scattered showers are likely from eastern Iowa into Minnesota,
wrapping around into eastern South Dakota and eastern Nebraska.
By Wednesday afternoon, the northern end of this system will have
moved off into the Great Lakes, leaving cloudy and cool conditions in
its wake. However the southern part of the system will continue to
generate thunderstorms across Missouri into southeast Kansas and
Oklahoma through the day. Severe storms and flooding rains are
possible in these areas.
Expect lows by Wednesday morning to range from cold upper 20s in
western South Dakota and the Nebraska Panhandle, to the 50s in
southern Missouri, with middle 30s to lower 40s forecast in eastern
Nebraska and southwest Iowa. Highs Wednesday afternoon will remain
rather chilly, holding in the 40s across South Dakota and northern
sections of Nebraska and Iowa, to the 50s and lower 60s from western
Nebraska into Kansas and Missouri.
